The Charpy three-point bend specimen is more convenient .
What Is the Charpy Impact Test? The Charpy impact test, sometimes called a V-notch test, is a comparative-style test used to define a material’s impact strength by determining how much energy is required to fracture a pre-prepared and standardized sample with a V-notch machined into it. See Figure 1 below: 1.1 These test methods describe notched-bar impact testing of metallic materials by the Charpy (simple-beam) test and the Izod (cantilever-beam) test. They give the requirements for: test specimens, test procedures, test reports, test machines (see Annex A1) verifying Charpy impact machines (see Annex A2), optional test specimen configurations .Charpy Impact Test ISO 179. Charpy Impact is a single point test that measures a materials resistance to impact from a swinging pendulum. Charpy impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken.

Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking. The Charpy test is a commonly used impact test. Lateral expansion. The lateral change in dimension of a Charpy impact specimen due to fracture. The dimension measured is the width opposite the v-notch (see Fig. 1-3).
How is the Charpy Impact Test performed? In a Charpy impact test, a notched (U-notch, V-notch, and double notched) material specimen is clamped in a test apparatus, and a pendulum is released to strike the notched area. The energy the material absorbs before its fracture is measured, indicating its impact strength.Engineers and researchers who have specialized Charpy testing needs will be the primary users of two new standards recently approved by ASTM International Committee E28 on Mechanical Testing. The new standards, E2248, Test Method for Impact Testing of Miniaturized Charpy V-Notch Specimens, and E2298, Test Method for Instrumented Impact Testing of Metallic .

The Charpy V-notch-CVN impact test also known as the Charpy V- notch test, is a standard test used to measure the impact energy (also referred to as notch toughness) absorbed by a material during fracture. The notch provides a point of stress concentration within the specimen and improves the reproducibility of the results.
